How to make the form front when it popup

Hi everybody,
When a process begin to run and step into the form activity, the form looks like foreground. But I can’t type anything into the text field which contains in the form until I click the form window.
I suffered this problem for several months and can’t handle it yet. Any suggestion is welcome!

Hello @zhangbw

Are you getting this popup at some particular position?? If yes, why done you close the popup and continue the execution t??

Is there any challenge for that?

Yes, the form must close after typing and the process will operate another software
